The Krebs Cycle
- the equation: acetyl-CoA + 3 NAD + FAD + ADP + HPO4-2 -------> 2 CO2 + CoA + 3 NADH+ + FADH+ + ATP
- Pyruvate is transported into the mitochondria and loses carbon dioxide to form acetyl-CoA, a two carbon molecule.
- chemical energy is released and captured in the form of NADH, FADH2, and ATP.
- During the Krebs Cycle pyruvic acid is broken down into carbon dioxide in a series of energy-extracted reactions.
- citric acid is broken down into a four molecule, more carbon dioxide is released.
electron transport chain
- The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.
- High-energy electrons from NADH and FADH2 are passed along the electron transport chain.
- oxygen is essential for getting rid of low-energy electron and hydrogen ions, th wastes of cellular respiration
